Introduction:
Virus infectious virus diseases mostly break out at the turn of seasons, such as Respiratory infectious disease , the flu , Hand-foot-mouth disease by Enterovirus, ect. All kinds of viruses always hind in somewhere we can not recognize. How to preventand eliminate the ubiquitous bacteria and viruses in our life? The UV in sunlight isvery effective at sterilization and disinfection, but how to sterilize the place that sunlightdoes not illuminate?
UV-A LED is a new trend which can achieve excellent effects on sterilization. In the past , we could only think of UV-C when we mentioned the use of LED sterilization. But now , welcome to our new partner-UV-A. Are you so surprised the sterilization of UV-A? Now, let's explore its amazing sterilization effects!
The Comparison of Principles of Sterilization Between UV-C and UV-A First
First, UV-C can kill bacteria because the band of light is 200-280nm which is invisibleto human eyes, also called "invisible light sterilization". However, another specific bandin UV-A which is around 405nm because it is visible to the human eyes, also is knownas ' visible light sterilization.
UV-A Oxidation Changes Property
1. The photosensitive molecules such as riboflavinand porphyrin in bacterial cells can absorbspecific light energy in UV-A.
2. Bacterial cells are oxidized to form active moleculessuch as OH, -02- and 02.
3. Bacterial cells are destroyed by damage to their cell walls.
UV-C Destroys DNA Directly
DNA in the bacterial nucleic acid is exposedto UV-C.
Bacterial DNA base breaks.
Bacterial cells are killed and cannot reproduce.
The Effects Test of UV-A Sterilization
| Lighting Source | Efficiency light Power(mW) | Illumination9(mW/cm²) | Irradiation Distance(CM) | Irradiation Time(h) | Exposure Dose(mj/cm²) | Reduction Rate of E.Coli |
| 405nm | 118150 | 2.70 | 350 | 0.5 | 19500 | 15.30% |
| 2 | 58490 | 69.20% | ||||
| 3 | 87730 | 99.90% |
The Human Injury Detection of UV-A
The detection result of UV-A in IEC62471 is an exemption,which proves that theharm of UV-A to human is negligible. So, it can be used as a light source of sterilizationcautiously when people in the room, due to the harmless propertry of UV-A to human body. UV-A can be used as a sterilizing light source for many consumer electronics andhome appliances because it does not degrade most organic compounds.
Advantages and Disadvantages Between UV-C and UV-A
UV-C:
High lethality will kill normal cellsand bacteria together
UV-C has certain risk, so users shouldbe careful when using it
Fast sterilization, the sterilizing rate is 99.9% in a short time
The damage to organic compounds byUV-C will lead to deterioration over time
Expensive
UV-A
Only do oxidative reaction with bacteriathat kills bacteria not normal cell
No harm to human. Don't need specialprotection measures.
The sterilizing rate is 99.9% in a longirradiation time
No light damage to most organiccompounds. It can be used for a long time
Cheap

FAQ
Q1: What is the Warranty for the lamps?
A1: For the lamps, we have more than 1 year warranty. If any quality problems on our side occured in this period, we will take on the shipping cost and replacement.
Q2: What is colour temperature?
A2: Our LED Lighting offer lamps in warm, pure, and pure and cool white with temperatures measured in Kelvin(K). Te lower the colour temperature is the light given by the LED.
Warm white = 2700k-3200k
Pure white = 4000k-5500k
Cool white = 6000k-7200k
Q3: what is CRI?
A3: CRI is a figure which feedback the real objects colors. Higher CRI with higher cost for LED Tudes , the CRI is mostly 70-75Ra, and 80Ra with hagher cost. But three are some suppliers write a high data to attract client, please note.
Q4: Can I change different lamp holder when I order? And how about the price?
A4: Yes. You can. And the lamp holder E14/E27/B22 is same for you.
Q5: Can we customize our brand and get support if we have our own market position?
A5: Yes. We welcome our customize, and please inform us your detailed mind on your market demand, we will discuss and propose helpful suggestion for you, t find the best solution for you.
